An important principle in folklorists study of legends (which many ghost stories fall under) is that the legend cannot be separated from its telling. That means that telling legends is generally a group process. For example, after someone tells a legend someone else might speak up to add some details that they heard; only to be interrupted by someone to contest a point, and so on. I suspect that in that framework there have always been people who play the role of the skeptic who provides alternative interpretations or the practical joker who makes light of the story.
